Proof step 6 from proof fits-law-bor-02 (previous step)

⊦ bcompl(band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))) = s2i(i2s(bcompl(band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))))), band(bcompl(s2i(sho1)), bcompl(s2i(sho2))) ∈short

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ i ∈short ↔ s2i(i2s(i)) = i
Proof step 8:
⊦ bcompl(band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))) = s2i(i2s(bcompl(band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))))), s2i(i2s(band(bcompl(s2i(sho1)), bcompl(s2i(sho2))))) = band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))

Rule argument

name: inshort-sis rotate: F subst: [i] → [band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))]

Additional information

Used terms: band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))
